Tap to focus #43

Open ThaJay opened 8 years ago

ThaJay commented 8 years ago

Is it possible to get native tap to focus with this? If not currently possible, how would I go about implementing it? I see https://github.com/lwansbrough/react-native-camera supports it, but i'd rather use one camera using component at the same time instead of implementing both.

@ThaJay what use case have you in mind?

ThaJay commented 8 years ago

My testers told me they had trouble getting the barcode in focus sometimes. I think it also has to do with holding the camera too close to the barcode in some cases, so it doesn't have the highest priority.

Same problem here, the scanner will not focus on close-up barcodes, requiring us to hold items far away from the camera. When the barcodes are small, it becomes almost impossible to scan correctly. This is a pretty high priority issue for us as all items have small barcodes.

Same problem too, our barcode size is 20cm* 20cm, it hard to focus when phone is too close to the code.
